I've got some quarter mile times from the local drag strip that I'm going to compare to. The down side of that is a little change in air temp & humidity can make a substantial difference in ETs. A more accurate before & after test would be on a dyno and there's no such thing around here. My truck currently runs mid to high 15s. I'll be racing weekend after next so I'll be able to make a comparison of sorts IF it arrives in time for me to get it installed before hand.
I'm a little skeptical too, that's why I'm taking the precautions I am to protect myself if it turns out to be snake oil. I've been documenting my mileage for several weeks now, city, highway & combination driving separately. I will do the same after so I'll take a few weeks for my comparison testing to be complete. No one will love it more than me if it in fact works as advertised. I don't blame folks for being skeptical but the results will speak for themselves. As I said before, I'll post the results when I have them, good OR bad.
